Beitknown that I, JonNR. .JUNKrN, a citizenof the United States, and 'aresident.

1of. Fairbanks, in the Territory of-Alaska,

United States of America, have made certain .new' and usefulImprovements in Steering Devices forAutomobiles, ofwhich the followingis a specification;

provement inthe steering devices of motor vehicles, and moreparticularly: to. that character of'steering devicesin .whichthe actualturning of" the Wheels 'is accomplished through power derived from themotor, un-

Power is applied to the shaftfD througli.

Inanycase theforward ,endofthe shaftF is providedwith a fric ition; wheel:F positioned 7. between spaced and .0 formed; radially-1 the samedegrees'of curvature andextension parl tiallyaround'the sleeveQgthespace between these vanes slightlyexceeding the diameter e fli i if tien h zth s mann r thefriction wheel F is constantly rotated,

and when 1t is desired to rotate the wheels in either one direction orthe other, the steerr ing post "A is correspondingly rotated to move thesleeve G longitudinally and bring one of the vanes C and G intoengagement with the friction 'wheelF.

and C I preferably providea bear g bl p This results in v causingrotative movement ofthe shaft D 6O securedxto' the steering.postby a nuta,:and" a mentioned.

The extentof this rotation will, however, be dependent upon the extent of therotation of the steering post, just as in the ordinary steeringmechanism, owing to the fact that the vanes G and C are radially formed.

, In any position of the parts in which the of the. vanes,

friction wheel F is out of contact with both the spring controlledsupplemental hlock Gr tends to prevent vibrations of-the machine from.displacing the neutral position; of the parts and accidental contact of.'the friction wheel with either of the v vanes.

I claim:iv Y o '1. In smear vehicle steering device, the combinationwith the steering post and steering knuckles, of a transverse shaft journaledinportions of the frame of the machine'and having a crankprovided with connections uniting the same with one of the steeringknuckles, a sleeve splined upon the said transverse shaft, a connectingrod having'a yoke engaging a portion of the sleeve,

a. crank secured to the steering post and having connection with thesaid connecting rod,"a pair of. spaced vanes radially formed upon thesaid splined sleeve, a power driven having a friction wheel 2. In asteering mechanism, the combinev tion with a steering post and thesteering knuckles, of a shaft journaled torotate and having a crankcontrolling the steering knuckles, a sleeve splined upon the said shaftandprovidedu with a pair ofvspaced vanes formed radially thereon andsimilarly curved, a power tion Wheel secured thereon and positioned inthe space between nections between the steering postand the splinedsleeve'whereby to control longitudi nal Ymovem'ent of the movement ofthe post. a 3. In a steering mechanism, the combination with a steeringpost and. steering knuckles, of a shaft journaled to rotate and havingconnections for controlling the steering knuckles, a sleeve splined uponthe shaft and having spaced vanes formed radially thereof and similarlycurved, a powershaft positioned in the space between .the vanes,

in the said bearing block and which receives the extremity of the saiddriven shaft to prevent accidental contact of the friction wheel andvanes, and connections between the steering post and the sleeve forcontrolling longitudinal movement of the sleeve, all for the purposedescribed.
